Django Anonymizer

Intro

This app helps you anonymize data in a database used for development of a Django
project.

It is common practice in develpment to use a database that is very similar in
content to the real data. The problem is that this can lead to having copies of
sensitive customer data on development machines. This Django app helps by
providing an easy and customizable way to anonymize data in your models.

The basic method is to go through all the models that you specify, and generate
fake data for all the fields specified. Introspection of the models will produce
an anonymizer that will attempt to provide sensible fake data for each field,
leaving you to tweak for your needs.

Please note that the methods provided may not be able to give full
anonymity. Even if you anonymize the names and other details of your customers,
there may well be enough data to identify them. Relationships between records in
the database are not altered, in order to preserve the characteristic structure
of data in your application, but this may leave you open to information leaks
which might not be acceptable for your data. This application should be good
enough for simpler policies like 'remove all real telephone numbers from the
database'.

An alternative approach to the problem of realistic amounts of test data for
development/tests is to populate a database from scratch - see django-poseur, django-mockups and django-autofixture. The disavantage of
that method is that the structure of the data - in terms of related models - can
be unrealistic.
